Garbage disposal installation includes removing any existing unit, mounting the new disposal on the sink flange, connecting the dishwasher drain line (if applicable), wiring the power supply, and testing the unit. We install disposals from 1/3 HP budget models up to 1 HP premium InSinkErator and Moen units. If your sink lacks a disposal-ready outlet, we coordinate electrical work for a switched outlet under the sink.

Garbage Disposal Installation in Pacifica — FAQ
What size garbage disposal do I need?
For most NorCal households (2-4 people), a 3/4 HP disposal handles daily use well. Families of 5+ or those who cook frequently should consider 1 HP for quieter, more powerful grinding.
Can a garbage disposal be added to any sink?
Most standard kitchen sinks with a 3.5-inch drain opening can accept a disposal. Undermount sinks and deep sinks may require specific mounting hardware.
Do I need a plumber or electrician for disposal installation?
A plumber handles the full installation. If you need a new switched outlet under the sink, an electrician is needed first. We coordinate this for you.
